Figure 5: Adoptive transfer of 1,25D3-treated CD8⁺ T cells into CD8-deficient recipients decreased cytokine levels in the BAL.

Cytokine levels in BAL fluid (mean+s.e.m.): (a) IL-4, (b) IL-5 and (c) IL-13. *P<0.05, **P<0.01; compared with sensitized and challenged CD8-deficient recipients that received no cells. Data (mean+s.e.m.) are from two to three experiments with three to four mice per experiment. General linear models were employed; pairwise comparisons were performed using t-tests derived from these models. #P<0.05, ##P<0.01, ###P<0.001 compared with sensitized and challenged CD8-deficient recipients that received CD8⁺ T cells differentiated in IL-2 alone, P values remained significant after correction for multiple comparisons (Benjamini–Hochberg⁵⁸ correction).
